TRACK "LEVEL,

Application filed February My invention relates to track levels for usein railway construction and is adapted to show the level of the rails.

It is van object of my invention to provideV a track .level ofJmetallicv construction which is insulated so as notl to electricallyconnect the rails and wherein the spirit level is supported in suchmanner that it may not easily get out of adjustment.

It is also an object to provide a supporting staff for one end of thelevel to indicate the difference in level between the two rails. 1t isalso desired that the means for noting` the space between the rails beplaced in such position as to be readily readable by the user.

Further objects and advantages arising from the particular constructionand arrangement of the parts will be brought out with` moreparticularity in the specification which fol-Y lows. Y

Referring to the drawing herewith7 Fig. 1V is a side elevat-ion of alevel embodying my construction shown in position upon the rails. Fig. 2is a top plan view thereof. Fig. 3 is central vertical section of thedevice. Fig. 4 is an end elevation thereof. Fig. 5 is an elevation ofthe end oppositerto that shown in Fig. 4. Fig. 6 is a vertical sectiontaken on the plane 6-6 of Fig. 3, and Fig. 7 is a side elevation of themeasuring stati' employed in connection with my invention. Like numeralsof reference indica-te like parts in all the views.

In construct-ing the body of my invention, I contemplate using a tubularmetallic body 1, which is preferably made rectangular in cross-section.The interior of the body is thus left unobstructed and an opening 2 isformed on the upper side adjacent one end thereof to provide a view ofthe spirit level which is mounted within the tubular body.

The two ends of the tubular body are closed by end plates 3 and 4. Theseplates are formed to tit about the ends of the tube, the plate 8 havingan upper portion 9 riveted or screwed to the body of the device and alower extension 5 lying along the lower side of the body 1 and connectedthereto by screws or rivets 6. Secured on the lower port-ion 5 of theend plate is a strip 7 of insulating material, adapted to rest upon therail and thus prevent the passage of an electric current from one railto the other where the tracks have been wired for electric blocksignals.

iece rigid material 8,- shaped like an angle iron, is connected to theplate 5 and 16, 1925. Serial No. 88,509.

downwardly extending arm thereon adapted to rest against the inner sideof the rail. This member is also made of some type of insulat-v ingmaterial.

The plate l at the opposite end of the body has an upper member 9',similar to the opposite plate, resting upon the upper'face of the bodymember. The plate closes the end of the tube and extends along the lowerside at 10 for connection therewith, and is attached to the body bymeans of screws 11. A plate ofinsulatin'g material 12'on the lower sideof the member 10 is adapted to rest upon the'rail and thus insulate theconnection.

The two end pla-tes vare Aformed with vertical` slots 13 therein at apoint spaced somewhat above the middle thereof, and'transversely ofthese slots the plate is recessed at 14: to receive a pin 15. A wire orrod16 of resilient-material is extendedlongitudinally ofthe interior ofthe level, the ends of said wire or rod being bent to connect about theypins 15. The `said wire y16 hason the end adjacent the plate 3 atension springl', which is connected to the wire 16 through the means ofa button 18 of insulating material, the end ofthe spring being woundabout the button and the wire 16 beingconnected through a centralopening in said button. vThis spring tends to hold t-he wire 16 in ataut position on a line directly connecting the pins 15 which areuniformly spaced from the lower side of the body.,

he spirit level 19 is secured to the wire 16 on the upper side .of saidwire and is preferably soldered or welded rigidly upon the wire. Thelevel is open on the upper side so as to be viewed through an opening 2by the operator. l

In ascertaining the difference in level be@ tween the adjacent rails. anadjustable-stati2 2O is arranged at the end of the body opposite thestop member 8.l and .it is contemplated that the stop member 8 will beplaced against.

Illu

the higher of the two rails and the. staff 2() will. be adjusted uponthe lower rail untill the body of the level is in a true level position.The said staff 2O is formed of a strip or plate of metal. the lower endof which is bent at right angles thereto to form a foot 21. The staff isslotted centrally at 22 to receive a cross bolt 23 having a thumb nut 24thereon. which may be tightened against the .stati foliold it in anyvertically adjusted posit-i n' The 'the main tlrliition t is' lli)graduated'as shown at, 25 in Fig; 7, so that: the height`- offthelevelabove thecfoot llof the staff may be indicated.
